Subject: [PATCH v6 11/22] clk: sunxi-ng: a64: Add minimum rate for PLL_MIPI
Date: Fri, 25 Jan 2019 01:28:49 +0530	[thread overview]
Message-ID: <20190124195900.22620-12-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190124195900.22620-1-jagan@amarulasolutions.com>

Minimum PLL used for MIPI is 500MHz, as per manual, but
lowering the min rate by 300MHz can result proper working
nkms divider with the help of desired dclock rate from
panel driver.
